<p>I wrote a comment. I think this is only P-medium, because the common issue with the examples is that a syntax error in the source (which is reported in a diagnostic) is somehow causing an ICE downstream after the parser does recovery</p>

<p>and so we are in this situation where we need to decide whether the lint is providing enough of a benefit that we should invest the effort to make it actually work properly with incremental comp. My brief review of the code last night led me to think that it was not a trivial fix</p>
